If you look really close at the PCB near where the 3 phase wires come off, do the little tiny chip resistors say â47Râ on them or â4R7â?
One of them is right under where it says âB1â on the PCB. Might have to use magnification or take a photo and zoom into the photo or post it
This number right here

If it has 4R7 ones, they need to be replaced

Hello good folks of this forum, first post here. kinda nervous #thebrain have an explanation to the cutouts and how to fix it. Long long long story short, swap the gate resistors and you wont have the cutout issues anymore.
The reason behind the cutouts of the 4.20 based vesc controllers are something called slew rate (Gamer43 will do a better explanation of that then I ever can, so wait for that if interested), basically when you you pull a shit ton of Amps and do so fast the DRV ship says see ya and cuts out. Sounds familiar⌠well that Is probable why you threw it in the fuck it bucket at the first place. hopefully you are to lazy to empty the fuck it bucket in the garbage and can still bring it back to life. because it is really quit f***** good when the cutouts are gone, and it can handle continues load surprisingly well, like really well!!! And to combat that you can change the gate resistor or the mosfets used. The cheapest and simplest solution for us garage folks is to change the gate resistors. Change all the 4.7 ohms resistors of the 4.20 plus to 22ohms and on the other 4.20 based versions to 47ohm. (again we will do a video and explain that better down in. y later onâŚ) The 4.20 plus uses âbetterâ mosfets thatâs why you need a lower value. Basically we have done maybe 50 hours trying to disprove our theory by messing around with settings and different hardware but yeah cutouts that wont happened even if you decide to strap the vesc to a truck and turn itâs wheels. (well I lied, we have not tried that but you get the point) Well as far as we got before i ran to mamma crying. Was with a 12s4p setup, dual 6374, sensored/hybrid foc, 80a motor max, 60a battery max on each side. doing so at the steepest hill I could find in the area and started from a standstill. And the only rule was: hit the throttle to max as fast as you could possibly could until you went flying up the hill, or the board cutout, or you went tree hugging.
Apart from that we have done, y anything imaginable to have the vesc cut out but nop, not a single cutout as long as you donât lower the resistor value, and if you do so just a tiny bit it will cut out instantly with just slightly aggressive settings and throttle movement. Yes even the plus version cuts out real easy. (the 6.6 Vescâs actually has the same issue with cutout but that is at like 80A (alot higher), so you kind of need to strap that to a truck to have it cutout, and very few people do that and we believe thatâs why people are not posting and crying about flying into a bush on the 6.6 vescs because of cutouts.)
Oh and I would go as far as to say, stay away from the plus versions their anti-sparks are not the most reliable in the worldâŚ
Damn I wanted to keep this short but I guess I messed upâŚ
Flipsky are now shipping all their 4.20 based Vescâs with the newer resistors. They just have not had time to update their website as they are in the middle of moving their entire factory. Have seen and gotten a few questions regarding it so I thought I might post it here.
If you want to go ahead and make the resistor swap yourself, I have 2-3 posts below and a video covering everything you need to know.

So I was looking around here.
I see three different packaging styles. And itâs a total guess, but that package with the dolphin on it and âV3.63â next to that, is probably the â47Râ / â470â version. My âFLIPSKYâ bag is the 4R7 version and the dolphin bag without âV3.63â is the â47Râ version. Neither of those have a version listed other than 4.20. Iâm going to guess and say itâs a good one with 47R. But you need to check and donât use it without fixing it if itâs a 4R7 model.

Itâs a cheap fix if it had 4R7 resistors, but itâs a major PITA

I sent mine to the Wizard for the swap/repair, and theyâre working great now.
